Building on Mac and Linux

[Gleeok]

That would be great!

I set it up yesterday for the 2.50.x branch. I'll commit them in a bit.


[edit]
Beware of just including everything though, you will get a wall of compiler nonsense. That's the reason I couldn't just add in a zc_unity.cpp and tell people they can just build that if they have an odd toolchain or platform or whatever. This is another reason I really, really hate global pollution, and I'm always anal-retentive about sneaky #defines or "using" in global scope.
